This is impossible using RPGMXP (which only has three layers, one of which needs to be a ground tile). If you could include some specialised tiles on this tileset then we would be able to make much better use of these trees. You could also include a verticle tesselation tile (b over e for example). This can be done with layers but a dedicated tile makes it much easier.
If, however, you are planning on doing some brand new trees for us then great. Depending on the size you go for we may not have this problem. 2x3 trees, for example, don't have this issue (although in that case it would be good to include tiles for the vertical overlap. The horizontal isn't needed).
