I think your hypothesis is correct. There is no doubt that some combination of spring and buffer will replicate the results achieved by the A5 system.
The question, at least to me, will the cost be comparable?
I can get into the BCM A5 for 99.50; their Carbine RE kit runs 57.95, but doesn't come with a QD endplate. So if I compare prices of their std end plate ($4.00) and their QD end plate ($16.95) their is a $12.95 price differential. Either take that amount from the A5 kit or add that amount to the Carbine kit, the results are the same, a $28.60 price differential.
Both those systems come with the 'basic' buffers - A5H0 (3.8oz) and Carbine (3.0oz). We can get those weights together by replacing the Carbine buffer with an H buffer ($22.95 at BCM) but there is still the spring difference. Some have talked of using the G Super 42 but that comes with a proprietary buffer so you need the combo @ $65.00 to get to A5HO. Other folks talk of using a Springco Blue @$19.95.
The bottom line is using a Super 42 kit sets you back $65.00; using a H buffer and Springco Spring (Red or Blue) will set you back $42.90. Both options are above the initial $28.60 price differential.
You can go about building the systems in different ways, but to make a fair comparison you should source parts from the same vendor as much as possible, and make it plug and play.
A final thought. I use a heavy rifle buffer (home built) in my service rifle. If I switched from the A2 stock to an adjustable, I could go with the A5 and a A5H4 buffer at essentially the same weight for $59.95
or go with the carbine system and a PWS H4 buffer for $89.95 plus spring. Again, the price of components would seemingly make the A5 a better deal.
