Tropical Flora Request for Sonic Colors map

I just started working on an rp/build map based on the Tropical Resort acts from Sonic Colors.

Here’s some WIP screenshots of an area I need flora for:

The problem is, Jukka K won’t allow me to use his palm tree models, which matched perfectly with those from the game, so I need replacements. I’ve got alot more progress done on the architecture, and some custom textures, but I don’t know how to make models, so any help would be highly appreciated and credit will be given in the map.
