Transitioning to IB FT from current PWM/prior IB experience

Current junior at west coast target/east coast semi-target. Struggling a bit on my possible full-time opportunities right now so I thought I can shoot my shot here and find out if there are any ways/luck/fate other than the posts I've already read. Going to be kind of long as I wanted to fully clarify the context here.

Didn't know anything about business when I went into college, decided on investment banking as the way to go, securing internships at two reputable boutique IB (tech/M&A) firms for freshman/sophomore summers. Had great experiences which solidified my choice for IB, albeit without really exploring anything else. While I have a great network and diverse extracurriculars/diversity, my gpa is unfortunately pretty low for IB (and lower during past spring). For that reason, I chose not to participate in the super accelerated cycle and only recruited within the regular cycle this fall but pretty limited within IBD as I chose to major in a "finance-related" field with all my technical experience stemming from internships and self-study/modeling.
Continued to explore other roles at big names for corporate banking and the like (didn't explore finance roles in tech), but ultimately settled on PWM at one of the top three for next summer in their corporate office. The FA convinced me to sign because as she's been in the game for a decent amount of time, business is growing to be more than she can handle alone and she wants someone with a finance background that she can mentor and transition into a junior partner in the next couple of years and pass her books on to. I trust her on this as she has great relationships with people I respect and know personally.
I'm open-minded about this opportunity and want to learn as much as possible anyways since I would be quite happy to continue if I do enjoy and excel at the job. However, I do want to see what my chances would be if I were to transition to IB for full time - the FA says (which I take with a grain of salt) that if I choose not to sign on full time with her, she'll be more than happy to connect me to her established contacts at her firm as well as other names for finance roles.

So my question goes: as contingency, if PWM doesn't work out for me, what should I do to prepare to exit to full time opportunities, allowing that I fully leverage my background/story/connections and perform well in interviews? And raise my gpa, of course. Interests would include but not limited to: IB, ER, AM/PB/IM, IR/CF in tech - just looking for somewhere that I can learn/grow extensively in a structured setting.
