Yes, I have and several others.
Short list of items you'll need.
New Engine mount & Gear legs along with cowl to gear fairings
Tail mount & assembly.
BTW, There will be plenty of offers to purchase your removed items.
Remount engine, some had to make cowl adjustments to fit, I did.
Remove rear panel to attach gear mount. May be an issue with attaching to VS braces if were cut during construction. I left mine uncut during original construction.
Remove original gear weldments from cabin. May be some additional work if your fuel lines & cabling are routing through them.
Fiberglass work to repair open gear weldments holes & cowl nose gear slot.
If you do a search you'll find more specific info.
Not alot of work, but you may be better off locating a TW 7 as so many come up for sale.
PM me if you'd like more detailed answers on the process.
