I wouldn't. I refuse to pay a repeating monthly fee to use a product I used to be able to buy with a one-time purchase price. Screw that. But you may still need to learn something that could do most of what PS could do, but it's free. Do a Google search for GIMP.
On the other hand, you do have a GTX1070. It does have 8GB memory, and my GTX1080 isn't all that much more powerful than your 1070. Even so, if I am going to do a render I KNOW will go to my CPU regardless of what I try, I just render it overnight or while I'm taking a long nap. I did this render a while back with 9 models in it all at the same time. It "only" took 6 hours using my CPU rendering it at 4096 x 2531 (for my UHD 65" 4K TV). You probably wouldn't be rendering at that high a resolution to begin with, so that should reduce your rendering time. The only "post processing" I did after it finished was adding the vignette border, which I did with a free program too.

But Rolmac is correct. Five models is going to tax the GPU. Depending on the complexity of the rest of the scene, you will probably have to render it using the CPU, or use the process Rolmac suggested. But I wouldn't pay the monthly recurring price Photoshop wants just to do renders here, or even for a Patreon site. I'm not making a living doing renders or selling games. It's a hobby. I wasn't able to go fully retired at 55 by throwing money away. Use an open source freeware program from the Internet. Did I mention GIMP?
And BTW, if you can learn how to use DAZ Studio, you can learn GIMP. DAZ Studio is one of the most convoluted, un-standardized, people-can-create-assets for-it-and-have-them-install-in-places-you-may-never-find-them-again application I have ever used. If I developed a program that confusing for any of the Air Force computer networks I worked on, I would have been Court's Martialed and sent to prison as a convicted felon.
