Is this change to a 45 to save on space? Do you mean the closet bend or the 90 after the bend and before the vent? Sorry just want to clarify.If you could replace the 90 nearest the toilet with a 45, that would be an improvement. But that may not fit.
Replacing a 90 with a 45 means less curves. Some will be needed, but if routing works as well with a 45, the 45 will be better. A horizontal to horizontal 90 should be the long type.For the vent fittings going from waste to vent

I see nothing to suggest a vent isnt needed dont see any 4 inch pipe or a 4 inch vent perhaps I missed a picture or drawing?@Reach4 I would love to join the toilet with the 4" waste line but I am worried that it would need to be vented properly. As I pointed out and @Jeff H Young mentioned, I do have a 4" main vent before the main p-trap and the toilet would be about 3 feet away. Is this sufficient enough to not put a vent? I do have a cleanout near there. I also wanted to mention I am adding a shower to the left of the toilet from the 2nd drawing. If I use a 3" wye with street elbow 45 and replace the long bend 90 like in this photo marked in yello, can I use this fitting to pipe the shower it would be dry vented as well?
This is awkward, but...
