Even if you found an extension to replace the floor plates, the flanges on the bottom of the magazine tube, plus the wider extensions themselves would prevent inserting them far enough into the magazine well to lock into place. (I just tried a compact magazine tube in a full size module.)

I even tried a compact magazine in a Wilson Compact grip module. They have a funnel flare at the bottom of the magwell and that allows the tube by itself to be inserted far enough to lock into place. But once the floor plate is attached to the tube, it won’t go in far enough to lock. I assume that any mag extension would cause the same problem.

If you were satisfied with a kludge job, you could shorten the grip at the bottom of the full size grip module.

If your goal is to use the mags you have instead of buying longer correctly fitting ones, the obvious, and least expensive, route would be to shorten your Carry and FS grip modules

You won't have any difficulty selling the 15 round magazines.

You can put an extended mag base on them, but they still won't fit into the full size grip module, because the 15 round is too short, and an extended base that attaches to a 15 round mag will still be too short. The lower lip of the mag where the base plate attaches doesn't change simply because you're using an extended (extra capacity) baseplate. The overall mag is longer with the extended baseplate, but the extended baseplate still fits to the bottom of the 15 round mag. This means it won't fit into the full size or carry grip module.

Pick up some 17 round magazines from Greg Cote: you can buy the ACT Armscor mags for twenty two bucks, and run them as is or with an extended baseplate like the Taran Tactical +5's.

I have a couple dozen of them, or so, with about half using Taran Tactical +5 bases (and Tarano's extra power mag springs).

Stock, they work fine, and they have the beveled dog ears, so will work in all the P320 grip modules (unlike the older mag baseplate

the older mags were made for the original grip module, and it's a frequent question here (and elsehwere) about how to use them in grip modules like the wilson, etc. Current Sig mags work fine, and use bevelled dog ears on the mag base plates; the Armscor (ACT) mags use beveled bases, too
I do note that the ACT mags have a slight bit of play between the mag extensions when used, and the base of the mag body. With rounds in the mag, it doesn't make any difference, and functionally it makes no difference.
I run Sig 21 round, and both Sig 17 and ACT 17 round mags with the Taran bases. There are other good bases, too; the taran tactical are just what I happen to run. I use these in competition; they've run without incident, equally as well as the factory mags.
I'd suggest buying one or two and wringing them out. They're half the price of sig factory mags. I prefer to have at least 10 spare mags for every handgun, so just the savings in the mags adds up quickly. Alternately, beat up the ACT mags at the range and save your factory for carry. I wouldn't have any concern running factory, or the ACT mags, for carry.

I can more than empathize with this. I've been going through and trying to sort out all my "gun stuff" recently and I've got all kinds of stuff that I either can't use, don't use, won't need, or pick your reason. Sounds like you and I both need to sell off some surplus gear.

Id say just keep them around along with a compact grip module...you never know when you might want something with a smaller profile for carry, and the P320 makes it easy to swap the grip modules back and forth. Options are nice.
