Well, he might have ended there while searching for women... so you'll never know... he just saw his allies in trouble and interfered... it isn't necessary that he planned to sneak with Raid Suit...
besides.... what supports my argument here that he's in base form is that:
1- Oda will first get rid of Beast Pirates clothes with him.
2- get back to the suit
3- THEN transform
Sanji is still in 1st step...
Let's not forget that Sanji SAID that he will ask Usopp/Franky to add some modifications to the suit... I do not believe that Oda will do that modification in design, then have Sanji appear with it "WITHOUT the transformation panels"... I feel the change in design will require Oda to re-do the transformation panels.. don't you agree?
