Create appimage for cliqz or script file

If not allowed please Delete…
Anyone interested in helping an old man out here?
I need “cliqz.en-US.release.x86_64.deb” converted to an appimage.
yes i know its discontinued and probably be a security risk but still would like to have a copy converted
and so would several of other people i assume. and i know all these other browsers are wonderful and do everything,
The developers have abandoned it and no response from them in any way.
the conversion process is way more than i can understand
i have the deb package backed up if it is not available anywhere
Would it not be great to have a Script to turn any .DEB package into an appimage, stopping and asking for the appropriate needed parts.
.Maybe such utility already exists?
