You mean the 45W unit? So far as I know, that is still limited to 5A at 5.1v, so that higher power wouldn't help.They already have the higher power rated PSU ready for this...Well.... The problem is that you need to UPS to be able to (re)charge while powering the Pi and anything else attached to it. To do that, the UPS is going to have to be able to draw more power than the Pi, etc. require to run. In the worst case, that means more than the rated 5A for a Pi5. The obvious alternative way to accomplish this is to connect the UPS to mains supply and then connect the Pi PSU to the UPS, and allow for additional PSUs to to be attached. What that is is a bog standard commercial UPS.Perhaps this already exists but...
My suggestion is a UPS battery backup for the Pi5 in case of power outages on system running 24/7.
There are UPS hats etc, but my preference is for something like a power bank that will power my P5 with NVME SSD drive plus some 2-3 Amp USB load. The power bank would receive its input from an 'Official' Pi5 power supply.
In other words this power bank would sit between an official Pi5 Supply and the Pi5 (or Pi4). This would both charge the battery and power the Pi, but when the mains goes down seamlessly switch to the battery backup.
With such a device you could very simply cobble together the true equivalent of a laptop with 'out of the box' components.
I can do this now with a small power bank with a PiZero or PiZero2W and a USB plug pack (if I have no load on the USB ports of the Pi) but haven't found a solution for the Pi5 that I've dared to try on my only P5.

At home, I use 1.5KVA units. For travel (if I want a UPS with me), I use a 350VA unit for any Pis I want to run.
There are starting to be lithium chemistry UPSes available, but they run pricey. I have some hopes that the Chinese move to Sodium Ion batteries for second tier electric vehicles will result in lighter (or smaller) Sodium Ion based UPSes to come on the market at reasonable prices and capacities....hopefully with longer full load run times than you get from the common SLA based UPSes now on the market.
Since these devices are "off the shelf" from a range of manufacturers, I can't see RPT designing their own.
Final note... You don't specify the run time you anticipate needing. That factor will determine how big (Wh) a unit you need.
