US public school physics PhD

1. There is a PI at my institute who is amazing. She doesn't have funds for more than her 2 current students.

2. My program is huge, and thus does not have the funds to support any PhD who doesn't get $$$ from their PI for research in the form of indefinite TA stipends. You are only ALLOWED to TA for your first 2 years. This is a huge point of concern for me: the only thing that kept me sane in my first year was teaching. I love it so much.

Given 2) would approaching her again with the following preposition be a legitimate way to work with her?

Working with her as her student but also working as an adjunct at a local community college?

concerns I have:

• this would make my PhD take longer than if I were doing research full time (although arguably more enjoyable for me given 2), not that I haven't loved my research experiences in the past, but 2-4 years without teaching sounds awful)
• would I be able to (reliably, there are only a few colleges in our area/not a city) make $20-30k as an adjunct to stay on par with what I would make as a TA now?

Edit after Buffy's points:

Regrading tuition the department says:

"If properly handled, PhD students do not pay tuitions, instead it is either waived, or paid by a research grant."

"Tuition costs for 6 credits at the in-state rate will be charged to the research grants as students move on to research appointments "

From the offer letter to the program:

"In addition to the offer of admission, we are offering you a position as a Teaching Assistant, for a maximum of four semesters. Thereafter, research grants are expected to provide research assistantships with a full stipend. We also will provide you with a full-tuition scholarship for the duration of your studies."

This is 2 year limit on TAing is actually rather common in larger departments nowadays.
