It might be; just not easy; and I haven't looked at the code in ages. But there seems to be similar options for preserving authorship in git-only (see below)

I'm sorry for your situation and hoping you migrate off SVN entirely, soon :)

Maybe you could look at how the _use_log_author and _add_author_from options work. I've forgotten their existence until now and I've never used them myself; but apparently they're still there.

Unfortunately, if you have other users using git-svn; it could be tricky to ensure they can see the same timestamps you see...
