Saturn Arcade stick with Mega Drive console

OK, so i got a little question. I have this stick sitting on my shelf collection dust, since i use another HORI stick for my Saturn gamin’.

I would like to mod this stick so i can use it with my SEGA Mega Drive, because i really dislike the official SEGA stick.
How hard of a mod would this be for someone with ZERO experience with any arcade stick modding? I have some soldering skills tho, but nothing to be proud of. :wink:
