Two Businesses on One Address (Local SEO GMB question)

Hello there,

I have few questions for all (local) SEO specialists.

TL;DR - Can you have on one business address registered multiple GMB profiles with different KWs (because different industry/different services) but with the same brand name (same ownership and brand recognition)? Thank you

Our main company has a well positioned and optimized GMB profile. We are number 1 in google's snack pack, have good reviews, active Q/A sections etc, registered office address, etc... . I can say we dominate the local market through our GMB profile, SERP and local service directories because (we cater local clients). Our company's name consists of a KW+Brandname[1] imagine Boring Monsters Ltd. (*Boring means boring/drilling activities).

We are in the last stage of acquiring another company in a completely different niche. Their name is just a Brandname[2] imagine Coderlytics, QickQoders,... they cater clients locally and globally in a very specific service/consulting niche. They have relatively well maintained GMB profile but almost no social presence, etc. Our goal is to "merge" two companies, close their HQ office, wind down their Ltd. and change their business address to our registered address because we are going to close the rental agreement with their landlord as soon as we finalize the acquisition and move their team to our office. My goal is to boost their digital presence (redirect old domain to the new website with new domain name, onsite+offsite SEO, digital marketing, direct marketing, etc.) one but I don't know what to do in regards their GMB profile.

That's why I am asking what should I do with their GMB profile ?
-Can I rename their old GMB profile name as KW+Brandname[1] i.e. Boring and Drilling Software Monsters Ltd. because we want to show we are the new owners and change their business address to the new one. Is it allowed to have multiple GMB profiles with similar names on one location? i.e. my main company's GMB profile Boring Monsters Ltd. as well as Boring Software Monsters Ltd. or we will get penalized by Google? Or I just need to add new services (software development) under my main Boring Monsters Ltd. GMB profile? According to my knowledge GMB profile names as tied to Business names, right ?

Maybe I am just over complicating, and I should just simply delete their GMB profile and create a new one and that's it?

Thanks for your comments !
