My company is looking to build a marketplace for peer to peer services. You could think Thumbtack type setup. We have identified two to three open-source platforms we could use as a base, but each have features the others don't have.
How difficult would it be to combine different elements from different platforms into one? Would this save time and make development easier, or would it be easier to build the other features from scratch?
Is this allowed under different open-source licenses?
