Way too expensive. A battery-backed DS1307 chip will cost you $4-5 on Amazon *and* will do the same as far as RTC is concerned. Of course, if you absolutely need GNSS that's different. Separate GNSS UART connected chip cost me $20 - a certain Neoway G7. And yes, you can attach both to your RPi. Reco
