I would doubt that is something that would be supported. Even before, if you used a new operating system the archives would not work.
Though, When Stardock impose to go from SDC to Impulse, it was told to customers that all applications archived with Stardock Central should be archived again under Impulse to be possible to be restored & used in future time ... i had spend hours to do so ...
What about the engagements stardock had with all his customers who pay subscriptions during years ??? and maybe have subscriptions till a few more years - it's in reference for the periods when Stardock encouraged to get few years subscritions to get some .suites in exchange ...) ???
When such products like Impulse are sold, everything must be sold with, and Stardock have a big responsability to let their customers the possibility to restore whatever they pay for during their subscriptions time.
For now i bought WindowBlinds 1 when it just came out for Windows 98, and if i want i still can re install it on a Win 98 PC by using SDC on it.
And for the future, i require Stardock to do whatever he has to do, to let me have the possibility of doing the same with any product i pay for during my subscribed periods (though since something like 1999 !!!! )
Stardock just have to remember who make them live !!!!!!!!!!!
