I’ve have made three boxes, one for my first Casita and again for my second Casita. Then I made one for my brother’s Casita."
Thanks Mike, and to all who have posted replies.

Mike's box is pretty much what I had in mind. I'll be checking with the local aluminum fabricators to see how economically feasable this deluxe route is.
The other real possiblity is a plastic garden-bench/storage thingy I found at Target. It's light, sturdy, water-tight and is just about the dimensions I had in mind. It would take a little modifying and I'd need to add a locking latch.
Whichever way I go, I'll need to take off the existing tank-bracket and battery mount. That's what the good lord made angle-grinders for.
Thanks too to those who cautioned me on adding tongue weight. Luckily our TrailMite is already a little light overall (no shower, no toilet, no jacuzzi, no beer tap) so I'm thinking that a ten pound box, ten pounds of jacks, an extension cord, clothes-line, water-hose, our little propane grill and perhaps a little more, won't put the lil thing too out of balance toward the front. But if Mike's set-up, with all his stuff and a couple of 30-pound+ bikes is okay, I think ours will be just fine. But worst case, I'd use it just for the lightest, bulkiest to free up some inside space.
I'll post pics and descriptions once I've got it done, whichever way I go.
