I am running out of West System epoxy and thinking of changing to MAS; but will they be compatible with each other--half way thur the construction of deep-v-runabout. Also it is hard to mix up very small batches of West at 5:1--1:2 seems a lot easier.

Good choice. As long as the old epoxy is completely cured and free of blush, that will work just fine. Note that a complete cure can take a lot longer than just cured enough to keep working. You'll also have to scuff up the surfaces with a light sanding to improve bonding to the fully-cured stuff.
