The modules in K1 and TSL follow different formats, so a dry copy-and-paste from one Modules folder to the other wouldn't work. Theoretically, it can be done, but that involves taking all of the model files of a specific module (as well as lightmaps and walkmeshes) and converting the mdls using mdlops and kaurora to work for the other game. Not to mention compiling it all into a .mod file. I'm not even sure if that would work. But even if it did, it would be porting and therefore illegal. Nothing short of modeling said area from scratch in 3dsmax in order to work in either K1/TSL format.
Short answer: Even if you somehow managed to get it to work, it's porting and therefore illegal, so no. Modeling an area from scratch in order to replicate an area in the game is unfeasible, so no to that as well.
The funniest thing about this sentence is that by the time you realize it doesn't say anything it's too late to stop reading it.
