The techniques you are using...copying the 000 folder over and manipulating the files are sometimes referred to as poor mans Global. Because PDMS is a tough little cookie and its databases self contained most of the time you will get away with this especially if you are careful about locking the project and taking precautions. However it is not unheard of for poor mans global to bite back and go wrong..... Global is expensive... no shame in taking the poor man's way :) But be careful.. !
To address your question.... The important thing is the number of the databases within the two MAS projects. As you probably know design elements using the catalogue look to the catalogue spec with their specification reference. On the command line this look like the name ... you type q spref....it says spref SPCO1 of SELE3 of blah blah.... actually what it really uses (as is often the case) is the reference number of this item. And the reference numbers in your catalogue need to be unique and match the expectations of the design database for it work properly. Reference numbers are a factor of the db number.
So if your MAS and the other MAS have the same dbnumbers and you try to mix and match you are probably going to struggle... as the same ref numbers may collide :(
