Welcome!
Yes, it would be relatively easy to find a replacement rear sight for a model 14-2. It will have a squared off front edge to the sight leaf (the part that attaches to the top strap), and the screw hole for the leaf was made in two locations so you would need the right version.
The rear sight blade (slide) comes in different heights and someone here can tell you the correct one for a model 14. Bonus is the sight covers all top strap holes
