That's not a shotgun !!!!!!

No such thing as a 22 Shotgun.
Custom build nowadays
If you can find one, yes.
Tough question, the Remington model 550 is a .22 rifle not a 12 gauge shotgun.
Pretty much a custom proposition. Do a google search on custom shotgun makers and start making phone calls.
75-275 USD
how much is a savage model 342 in 22 hornet worth pre 1968
Can't be answered without a detailed description of all markings, finish, condition, accessories, box, papers, etc..
AFAIK, there has never been a 22 gauge shotgun. 20 and 24 yes, but no 22. A 20 gauge would put a small hole in a ceiling, depending on how construced and the type of ammunition use. Caliber refers to rifles and handguns. A 22 caliber will not do what you mention.
Model 24 is a semi-auto 22.
