Since you're a big guy -- much bigger than me anyhow -- I would think the X20 in the right belt bag should work pretty well for you.
I used to have a Tamrac Velocity 3(?) semi-sling-type bag that can be converted into a large-ish belt/waist bag back when I was using a Canon G3 and then Nikon D70 (before the metal D rings for the strap completely wore out). There weren't as many options for waist/belt (or even sling) bags back then, and I got the Tamrac mainly as a sling-type bag that I occasionally tried using as waist/belt bag. For me (at just ~5'7" and on the slimmer side.. back then anyway ), it was just too big to use as belt bag most times -- it was ok enough when I'm standing/walking, but problematic as soon as I sit or crouch (or bend) down (unless I keep it behind me on my backside perhaps). But if you only need something to store an X20 (or similar) and not too much else, you wouldn't need a bag that big anyway -- I used to fit the G3 + 420EX speedlight (attached!) + both Canon's wide and tele converters for the G-series (w/ one attached) and whatever other little nicnacks before switching to D70 + attached lens + Sigma 70-200 f/2.8 (very snuggly alongside) + speedlight in front compartment + add-on pouch for a small prime like 35 f/2 or 85 f/1.8. Of course, I couldn't possibly use it as waist/belt bag w/ the much heftier DSLR kit, LOL -- and probably neither can you w/out the bag pull your pants down perhaps...
Anyway, yeah, I imagine a small belt bag just for the X20 and a few accessories (much like how you'd use a fanny pack) should work fine, especially for someone your size. Back then (before and around when the D-Rebel/300 and D70 first came out), Lowepro's D-Res series was another popular option for this sort of thing though I never tried their waist/belt bags in this manner -- I did have a D-Res pouch-type bag that can latch onto a belt, and used that for the small SLR prime to be attached to the Tamrac V3 (or separately on its own strap when I want to walk around w/ just the DSLR+attached lens and a prime), and even that pouch bag could've been used for just the Canon G3 alone, IIRC...
Just another amateur learning to paint w/ "the light of the world".
