Yes, I would do this.
The mistake some make is just change the routine, looking for progress when they plataeu, then if that doesn't work after 3-4 weeks, change it again, but I know from experience it's often calories that fall short and cause the issue, not the routine, so all the routine changes yield nothing, except a prolonged plateau and possibly some new understanding of things you don't like doing.
I would go one of two ways.
if you're eating 6 times a day, add another 300 calories per day, working out as 6 seperate 50 calorie increases with each meal.
These are two possible ways.
1. 5g protein, 5g carbs, 1g fat, (49 calories)
2. 5g carbs, 3-4g fat, (47-56 calories)
To bulk, you only really need an upper limit of 1.2g per lb of bodyweight with protein and 1.5g max, so I'd go for the first option to start, but when you next plateau if you think your protein is good, use option 2 or stick with option 1 for another time, then reassess next plateau.
You don't need to be jacking the calories up big time, as your body wouldn't use them all and you'd convert a lot of them to fat, the excess gradually becoming less over time, when your body would use more calories to bulk.
Too many people plataeu early on in the process and when they read what big guys eat they get tempted to copy it, when there is no need, as if they want to be that big, then they'll eat like that when the time comes.
If you're eating 5 times a day, use one of the two methods described, than add another meal in about 2-3 hours after the last, with 200-300 calories in it.
Hopefully that all makes sense
