Is there something to be aware of when renaming Types, Methods, Pramaters and Fields?

[SurmanPP]

I want to write a program to obfuscation (re)mapping programs and this library seems promising. The basic idea of the process is clear:
Read a lookup table.
Go through each entry.
Find the Def.
Change the Name accordingly.

However it seems that for example generic type fields require special care(#478). Is there more to be aware of? What about changing the Namespace? Do the same rules apply?

If you know of the existence of such program that does exactly what I am trying to do I would also be happy to know.

Thank you in advance!
