Quick answer is no. FRS radios are FRS radios and GMRS radios are GMRS radios.
Longer Answer-
"Dual Service" radios stopped being allowed to be sold in 2017 when they made a bunch of changes to the GMRS/FRS rules. While GMRS FRS share the same simplex frequencies you can't use a GMRS radio without a license. To be legal you would need to buy FRS radios for now then when you decide to finally get licensed you would need to pickup some GMRS radios to take advantage of the expanded capabilities of GMRS then you could hand out FRS radios to those unlicensed, if the other people are your family then they can use GMRS radios since they are covered under your license.
If it was me Id just spring for the license, install a mobile unit in your vehicle (way more power and external antenna options and not having to deal with the batteries in handhelds) and then a few FRS handhelds to hand out to unlicensed friends or for spotting. That way your bases are covered.
All that being said no one would be able to tell if you were using a Midland GMRS handheld without a license. The way the service is makes enforcement nearly impossible, which is the case for a lot of radio rules/regs.
