Repairing rotting floor - are squares OK?

Hey guys, I found a section of our floor was rotted away. I cut it out, and fortunately there is good wood on either side of the rot that I can drill in to.

I attached a picture to this post. I cut all of the flooring out between two joists. My plan is to put sister joists along side the existing joists and lay new flooring on top of it.

My question is, is it OK to attach the joists on either end to form a traditional square, like you would use for repairing rotting floor in a house? That would give the new flooring even more stability, but I'm wondering if I should avoid doing that so that the joists will be able to flex a little bit during travel.

In the picture the red lines are where I'm going to be putting sister joists, and the blue lines are where I'm wondering if it's OK to put them.

I hope that question makes sense! Appreciate the feedback.
