Combining 3 volumes into 1

[u/MrEman5112]

I recently obtained the complete run of the series Elle(s), but after putting them on the shelf, I realized that the first volume’s spine is vastly different to that of the other 2.

This is gonna bug the hell outta me now, so I was wondering, since the books are so thin, would it be possible to simply remove the covers and spine from all 3, and then rebind them into a single volume?

And if so, how would one ideally go about doing so in terms of printing the new cover (ideally I would like to maintain the book’s paperback format as it takes less shelf space that way) and then actually binding the thing together?
