What would you do? TT to ST tube diameters

Hi everyone! I'm new to the forums and also new to framebuilding.

I was wondering if someone could help me in regards to joining Top Tube and Seat Tube. For some reason I've been designing the frame with a 31.7mm TT and a 29.6mm ST but that doesn't feel like a great joint to me. What would you do? Would you get a smaller TT or a wider ST or maybe not do anything about it? Even tubes with the same diameter feels like it won't be ideal right?

It's a gravel type of bike and I've attached what it currently looks like this in RattleCad. Lowered the seat stays so you could see the current issue. Oh, and it will be fillet brazed.

Would love some feedback for a newbe like me!

Noticed I wasn't allowed to post images yet. Doh!

Thanks guys!
