Zr750 in a rigid frame?

I've seen plenty of cb750bemgomes in rigid style chopper frames. Has anyone ever put a zr750 engine in a rigid style chopper frames? Think it'd be pretty cool to see one all bones like that. If no one has then why not? It could be a competitor to the cb750 chop and way more rare. Is it because all the vacuum lines and bs? Get rid of all of that stuff like most of us already have. Would love to see one.

These guys have weld-on hardtail frame sections, including for the 750/4.

Same engine as the earlier Z650/Z750/GPZ750 and i've seen hundreds of those chopped over the years so not anything unusual.

Thank you
