I'm late to this party.... but... do you really want all the pumpkin in your boil kettle? That sounds like a nightmare.
As a rule of thumb I'd say never use goopy ingredients without a secondary fermentation. GF brewing is hard enough without subjecting yourself to primary-only, and adding a secondary is really easy. You can even use your bottling bucket as an intermediate so you can rinse out your primary and rack back into it for secondary.
