My opinion is that I wouldnt go straight into a BB style macro split that is heavy in carbs straight out of keto. I've been on keto diets and have had more favourable results gradually bumping up my carbs rather than going all in from day one. I was previously a fat guy so have learned to be cautious with my carb intake as going back to a more 'normal' level of carb consumption after minimal carb intake lead to rapid fat gain.
I have successfully managed to come off a keto diet and remain lean. Initially I kept my calorie intake consistent but replaced some fat calories with carb calories. I dropped 200 calories of fat from my post workout meal and added 200 calories of starchy carbs. I stayed like that for a few weeks and monitored my progress. I didn't gain fat so I removed all added fats from my post workout meal and replaced them with starchy carbs and again stayed like that for a few weeks and monitored progress. Again I didn't gain fat but I had a noticible increase in my energy levels. I was waking up in the morning feeling far more energetic than when I was consuming minimal carbs. I was still avoiding starchy carbs for all meals except the post workout one so I then used the same approach for my pre workout meal.
I've never really gone for a get huge style bulk but I have noticed decent increases in lean mass by adding a couple of hundred extra calories of carbs to my post workout meal every 1-2 weeks for an 8 week period. Might be worth a try?
I know everyone is different but personally I think going from keto to high carb overnight isn't a good approach. In fact I'd go as far as saying that nobody who properly trains should ever do a keto diet.
