Three remote internships within one summer?

A bit of a weird question here. I'm currently a rising Junior in a non-target university (target for boutique firms but not MBB), and know that I want to pursue Management Consulting post-grad. During my sophomore year, I landed an internship for a VC that extended an offer to work remotely and fewer hours through the summer - allowing me to stay with them and pursue additional positions if desired.

I then took the liberty to join an AI SaaS startup as a Business Analyst Intern and began my work with them around 3 weeks ago. Also 100% remote, probably around 15 hrs per week MAX. 

As of last night, I received an offer from a small M&A firm as an Intern for this summer and perhaps through the fall semester. Also remote, hours not confirmed yet. This is also the only paid position, other than the VC which gives a bit of carry and a percentage of earnings on each investment I assist with. 

My question is whether maintaining all three positions will look messy, and perhaps take away from how seriously employers view these positions. Is there any reason to assume a detriment to working all three if I believe the workload and time commitments are manageable?

TIA.
