In any case, the idea you suggest was tried and quickly abandoned once the impact was seen. There is a place for some bps with resources from multiple locations but only in a limited capacity.
I agree that each planet's primary BPs should use only resources readily available on that that planet, especially when the planet is starting out. So, for instance, the Ark weapon BPs must only use materials that will continue to be available on Ark.
However, what the OP is talking about is different. The only "multi planet" BP I'm aware of is welding wire. If we look at the success of the welding wire BP, it has maintained a consistent MU for alternative and ospra since the WW BP was released, in spite of the fact that these are both very abundant and easy to find minerals on their respective planets. Now each of these ingots do have uses in other BPs, but I believe the main sink for each is welding wire. I also believe the majority of our ospra ends up on Calypso. Ospra is one of the only Ark minerals (perhaps the only one) that has consistently had a high demand on Calypso. Now if you notice, the third mineral in WW is the universal mineral Lysterium which 1) is so abundant that the WW isn't going to affect its price and 2) is present on all planets. This "multi-planet" BP is set up to preferentially help two smaller, new planets (Ark and RT), and it has done that.
New planets' economies need all the help they can get to be competitive, so I think these multi-planet BPs can be extremely good, as long as they're designed properly.
