have celestron astromaster 114eq . worth modifying ?

so i have this celestron astromaster 114eq i didn't buy it

it isn’t actually a Newtonian. It’s a Bird-Jones im told

Celestron’s design places the corrector lens inside the focuser

my question is is there a way to change the mirrors and elements and reuse the 5" tube to make this a better telescope or would i be better of starting from scratch

my main usage is with my dslr is this a bad combination ?
