Charater Creation Questions

You're in

And a fifth player has joined us! Full up party

Before combat starts would it be alright to switch up my equipment and feat selection a bit to better represent my god?

My plan: Get a longsword and shield instead of a heavy flail (Iomedae's favored weapon is a longsword), and switch weapon focus over to longsword

this is acceptable

Thank you. I was looking into the God I'd chosen and thought this would fit better

I'm all for fluff and making the character work over any mechanics and rules :D
