access hatch for rear of Scupper Pro TW

hey folks, i have an idea of mouting the transducer for my new FF in the back end of the scupper pro TW. however to get back there i need access and was considering installing an access hatch at the back / bottom of the rear tankwell. do you think this is a good idea? i'll have access to the back but i don't know if this will change the strength of the rear. whatttdaya think?
