I don't know what to recommend, but that was a fun trip back in time. I was 13 and I actually liked Def Leppard!

One thing I can tell you about that sound is IMO you'll need the type of synth where it's a self-contained tone generator triggered by your bass notes, rather than the kind where it is only filtering, fuzzing, and altering your bass's natural tone. I'm sure you've already searched on the word "synth" and read the various threads explaining that distinction and which pedals operate which way.
