Good idea? Maybe.

Epoxy is VERY application dependent. Also some pool epoxies are very low quality. Read through the literature at Kelley Technical, and then decide. Either do it yourself OR use a contractor who can show you some 3 year old prior epoxy jobs. Last time I checked, Doheny's had the lowest prices on Kelley's epoxy.

Kelley has good products; so do some other companies, but I don't know which they are.
