If we are going by alliances, it would behoove both kara and kami to allow rangers to use their TPs, maybe for a higher cost, but still allow.
After all if I recall what I have read correctly, the story is rangers' primary concern is homins vs kitin, and rarely if ever take sides. When they do, they will side in a homin disagreement, it tends to take side to balance power or gross injustice.
It benefits both to have rangers to keep the other side in check.
I do know this will never happen.
This would be cool and sounds like fun, however, Then everyone in the game would like to become a Ranger and that would not be very much fun either imo :/
