A guy could cut this in two places to make it WSM like, with a lower charcoal bowl, a middle section, and a removable lid. A length of strap steel could be welded on the inner circumference of the lower bowl and lid to make it a piece that could be disassembled. Just a thought.
at 23" you'll be able to use 22.5" weber grates.
Make sure you leave enough room uner the chrcoal grate/basket for ash to accumulate.
Put some legs on it and you're stylin'!
If you want to keep it a one piece unit a thought I had would be to
cut another small door opening under the main door so you have access to the fire area.
I really give you credit for your idea.
Git R Done !!
Just my 2 cents
