Seconded.  New code should be GPLv2+ unless you have a really good
reason for something else.

Keeping the original license in a derivative work is a really good
reason (assuming it's compatible to GPLv2; if it's not, we can't use the
derivative work anyway).

LGPLv2+ license for code meant to be linked into differently licensed
other projects may be a good reason.

Other reasons exist.

Whatever your reason is, you need to explain it.
