AWD will make the car far more expensive, even heavier than its current porcine self, and hurt (already mediocre) fuel economy without giving much benefit to handling. Same story with the LFX. And at that point, it'd be knocking on the "softened styling for Europe" ATS's door. The transmissions in the GS aren't GM units to begin with. And the manual bogs down off the line, so the GS isn't even the fastest Buick on offer. The Verano Turbo is. The Regal eAssist is tied with the bigger LaCrosse for best fuel economy in the Buick line, as well, so there isn't much advantage with the Regal on that front, either. Sure, the GS's handling is great, but it would be better without all the expensive technical wizardry that results in more compromises if it were RWD.
The Regal is just too much of a compromise car in a dying segment (FWD premium midsize performance sedans). It's a good car, itself, but in its current setup, it does get lost between the very likeable Verano and the luscious-looking LaCrosse. It's clear that GM is still trying to find an audience for this car, and it's not working too well. 12% of Regal sales going to the GS is good, but only if volume overall is good. And Regal volume is pretty dismal at this point.
I don't really think Opel benefits much from the Regal. They can't when it comes to volume because the car is produced in Canada now, and shares only one engine with the Insignia. Suppliers are different, tooling is different, and the car is built in a different plant than its US platform mate, the Chevy Malibu, so economies of scale are reduced, since two sets of tooling for the different locations are necessary. Buick and Opel should only team up where the partnership works. The Verano/Astra works. The Encore/Mokka might. The Regal/Insignia doesn't (except in China, which is a whole different banana and complicated since Opel is setting up shop there, too).
A RWD Regal replacement on Alpha wouldn't hurt the ATS if the car were, say, 190" long or so. If it were between the ATS and Alpha+ CTS in size, it'd slot in between the Verano and LaCrosse, but not be just another FWD premium mainstreamer. The performance potential would be greater, and it could mop up customers that don't want an ATS due to its compact size, but don't want to stretch to where the new CTS will be priced. The LaCrosse needs to get a little bigger next time around (e.g., trunk space), anyway, and would be a much different animal, so it'd be further out of the way from a RWD Regal.
Styling and marketing are the biggest factors for a car like an Alpha+ Regal (see: Charger vs. 300). It can work if it ISN'T badge-engineered. Someone earlier brought up VW, and I think they have a point. Product overlap isn't so much a problem as lack of product differentiation. A RWD Regal could be styled much better than the current car and be different enough from the cars above it and below it in the line to carve out its own respectable niche.
As for Opel's issues, they wouldn't need to build a new plant at all, just add a line to one of their current underused plants across Europe. Plus, if Opel hopes to get out of Chevrolet's way, they'll need a vehicle to sort of seal the deal that their upscale push is for real. An Alpha+ car would certainly help more in Europe than a rebadged FWD LaCrosse would.
In all, I think a RWD Regal would be a great idea, a great way to mix things up in the Buick line. Lots of power for a GNX/GN/T-Type redux could be added easily. AWD could be added easily, since the platform is lighter in weight. And an Alpha-based CUV to slot in the massive gap between the Encore and Enclave would be good, too. Alpha's body style flexibility would mean costs could be spread out over more units, as well.
Remember that Epsilon II's costs are being defrayed over two versions of the platform (a platform on which a Buick already rides), much more volume, and the Malibu is already a global player that's saved the company from having to design an Epica, too. If the Insignia can't make a business case for itself in Europe/China/Australia without 20,000 additional units in the US, then maybe it is time to put Opel down.
Think of an Alpha Regal as a direct replacement for the first-generation CTS. Then it begins to make more sense.
