There is of course the upcoming Alpair8 series that will hopefully include option for (at least one formulation of ) paper cones.
Then the 10P, scheduled to be available mid to late next month
FWIW, even though a much lower price point driver, I'd characterize the late CSS EL70 to as close to a paper version of the A7 as anything Mark has yet released.
As Zia has noted, A6P and A7 are both quite good drivers - depending on the application, either should work fine.
Mark is continuing to expand his product line with models including option for cone materials - eg Alpair6 in metal and paper, and the CHR /CHP70, and as noted above the new 10P. So far I've only had the opportunity to taste test the 6 in both - and they definitely have different flavors. The current version of CHP has an intentional tailoring of the upper several octaves that some folks (myself included) might find a bit "soft / dark". As Mark is constantly revising his drivers, this might change in the future.
The 7 is so far my overall favorite MA branded driver- I'm currently running them in 2 different systems, but if you'd rather not wait to try one of Mark's drivers, the CHR70A price is a viable option.
Whichever model you might select, be aware that lengthy, careful break-in is required - don't judge any of Mark's drivers on performance fresh out of the box.
too many choices
