You may be able to drill new holes in the spindle closer to the center to mount the v calipers, but the mount gets thinner closer to the center so there won’t be a surface to mount to.
Where did you get that model? I was trying to find one because I was tossing around the idea of making myself custom spindles to mount v calipers to.
I would not drill the spindle and put load on a point the engineers never intended to carry the stresses of a bracket.
I did have a MovIT kit which cut off the upper ear and mounted the upper bracket using the bearing pack bolt to mount Brembo Big Reds off a Porsche. They did use the lower ear to mount the bracket.
now custom spindles just for those calipers is getting a little silly, unless of course you have access to that kind of machinery, then you could incorporate the drop geometry like the LG pieces.
If you just imagine a bracket similar to this:
that offsets the mounting location towards the spindle centerline, and also lowers the caliper (so you can tell people you improved the center of gravity). it would make for an easy, bolt on solution. assuming there is enough room to push the bracket in before hitting the spindle.

I make Molds and prototype parts for a living and program a 5 axis so for me it’s no big deal.
In order to use a bracket like you suggest the mounting location of the caliper mount will be moved towards the engine, which I’m not sure if is possible since the caliper must remain in the center of the rotor.
Maybe you can pull it off but I don’t think you will be able to.
I'm going to pivot here after looking some more and thinking like a responsible person.
BOTH front CTSV1 calipers (4pot) can be purchased new for less than the price of 1 6pot.
this caliper on the f body can be ran with an OEM C6z rotor.
I think that this route will be a better proof of concept for me. as if this combination works, then I would be able to simply upgrade the front rotors and calipers if I ever saw fit.

Ah I see what you mean, you're worried about the flat bracket,
I was talking more about the mounting locations from a straight on view.
Your concern is still easily solved, although not as simple of a part. It would be similar to the GTO bracket, or the old rear bracket for the G8 brembo swap
Question: How do any of these calipers (C5/C6Z06/CTS-V/Wilwood) compare to the Brembo produced radial mount 4 piston calipers which come on the Porsche 911/996. Yes, they will require a custom bracket but their performance is amazing (never heard of any Porsche guys complaining about their brakes).

I'm only interested in this because it looks cool, and its a BBK you can buy pads and rotors for at autozone for peanuts
The MovIt kit I mention on my C5 was a very noticeable upgrade over factory. It used the Brembo Big Red calipers with 322mm Porsche rings using a custom hat on the 2 piece rotor.
The kit TCE posted from Wilwood can be run with OEM rotors. The front only kit is very reasonably priced. Essex also has a kit which can be run with OEM rotors. I believe the pad shapes for both calipers is rather common. The pads also lasted longer on my MovIt BBK and I would expect the same from the Essex and Wilwoods kits.
I understand the desire to use OEM parts which one of the reasons I liked the MovIt kit but getting a set of pads for the aftermarket calipers isn't a major problem these days. If I had a daily driver C5, I would be very interested in the Wilwood kit.
As a hotrodder I do applaud the effort to make your own BBK.
