I can't tell you how feasible it would be, but unless you want to 
implement it yourself, you'll probably have to do some more 
convincing in order to get someone to implement it for you. As you 
said yourself, the potential use cases for such a multi-file 
buffer are easily covered by other means. There is `multi-occur` 
for searching in multiple buffers, there are front-ends to e.g., 
ripgrep (I use `counsel-rg` self) to search through multiple files 
and with `wgrep` you can then edit those occurrences in one go. (I 
use `multiple-cursors`, but you can also do a search and replace 
in the multi-occur buffer.)

The point is, for something like this to be implemented, there 
needs to be someone to do it. And for something that appears to be 
quite a fundamental change with relatively little gain, it's 
unlikely you'll find an experienced Emacs dev to pick up the task.
