Set the compression to 15 on one side, 12.5 on the other, reduce the rebound to 7 on both. Then fit some KYBs that are actually sprung and valved for your very light weight.
Summary to you question; no. If the rest of the bike is good - it (fork swap) is worth it. If it is a worn out 12yr old bike then it is not worth it. Start saving.
Week before last I had a great weekend riding my old but rejuvenated 07 which has better suspension than my 2021 beta.
I'm thinking of installing the race tech gold valves and seeing if the suspension works acceptably, otherwise I think the solution will be to change them. I looked at a 47mm show on ebay and the value is attractive. I think even the original ones would work better, then later I change the springs and do the race tech genetics on them too
