Can I plant a Acoma & Tonto Crape Myrtle together (same hole) to produce a tree with pink and white blooms?

This will, usually, result in the death of one or both shrubs. I would not attempt this. A better option will be to graft two colored branches of crape myrtle onto a another of the species. This will allow you to have two different colors on the same tree without competition.
