If you are talking about using the maximum number of modular, non-AR180 proprietary parts on an AR180 based receiver, the Jard J180 Builder Kit may meet your requirement, sold by Sylvestre Sporting Goods in Canada. Every part inside the receiver is included and already installed, including a fairly nice trigger that can optionally be replaced with any standard AR trigger, and a pistol grip that can be swapped for any non-beavertail pistol grip. It uses any buffer tube based stock, and since there is nothing in the buffer you could use a folding adapter or buffer tube to 1913 adapter and a 1913 stock. The 180 recoil harvesting system is fed by a gas tube instead of a piston, so the firearm uses any standard AR-15 barrel, gas block, gas tube, and handguard.
If the aesthetics don't meet your liking, or you would rather buy a made in Canada solution, SBI is working on an upper and DI BCG to match their WK lower that would allow use of a similar number of standardized parts.
