Exactly that.I say.

But unless you plan on riding gravel or commuting or just want something ugly enough it won't be stolen from outside the pub don't buy any XL size 26er. Find a small.
For razzing about on and not taking anything too seriously hardtails like the old late 90s chameleons in small with a short stem, 100mm fork and risers were a bazillion times more direct than modern hardtails are. Modern long reach, longer wheelbase, longer fork travel and slacker H/As combined with bigger wheels makes them a lot more stable at speed but the downside is they become an absolute chore to pop the front and bunny hop. If your hardtail riding back in the 90s was anything like mine I'd guess those are probably the traits you'd have liked most about your old Chameleon.
S'pose it also depends what your definition of "fun" is now tho.
Do it.
