Use Workers for Rewrite Rules

We wanted to see if using workers for replacing our Rewrite Rules from an old server and Page Rules in Cloudflare is worth. We are running out of Page Rules. I have a list of RewriteRules, for example:

RewriteRule ^/facultysummit2013/?$ India Faculty Summit 2013 - Microsoft Research [R,L]

RewriteRule ^/chapters/(.)$ /public/chapters/$1 [R,L]

We have over 500 RewriteRules to convert. Can anyone suggest what would be the best approach? Should we use Workers for this purpose or not?
