This was actually something I looked into when I first obtained Blitz3D. The first hurdle is what the landscape is going to be made of. Blitz's own terrains have fantastic LOD (Level of Detail) handling, but unfortunately you will notice "seams" between the tiles where the polygons are approximated leaving ugly voids. The second obvious hurdle is poly count. With a mesh you won't have the problems terrains have, but unless you have a mammoth machine with plenty of memory, your poor renderer might suffer under the strain.
Its not a completely bad idea though, as long as you can create a workable LOD system. This entails cutting down polygon counts for distant objects either by using premade lower-poly models or dynamically altering the model (much like Blitz terrain). But I guess it all depends on what you want each tile to contain. Perhaps if you could give a few more details on what you want to achieve?
