Another Bathroom Vent/Drain Question

[b-rye]

I've got a 50's ranch that has the typical single stack. Originally the toilet drained into the stack with the inlet port receiving the tub, lav, and kitchen sink. I'm going to reconfigure the layout while still using the single stack location. Looking at the wet wall in the bathroom, from left to right it will go lav, toilet, tub. My question is can I have the tub and kitchen sink upstream from the toilet and then continue on to the waste stack. The lav will use the stack. Every fixture will be vented individually and tie into the 3 inch dry vent. Some info I have read states that you have to run the tub in front of the toilet vent. I have attached a picture of a side view and birds eye. Thanks

I dont see an issue. As long as each fixture is individually vented, you can tie them in to the branch however you want.
