Fullscreen when only one window in workspace?

[YourAverageMo]

just got aerospace and am loving it so far! I find my self hitting alt-shift-f to 'fullscreen --no-outer-gaps' all the time when i am just using a single window on the workspace. and i have 10px gaps all around except in fullscreen (0px gaps).

i like the look and feel of no gaps when i only have a single app open like chrome. i was curious if its possible dynamically set gaps depending on if there are > 1 window in the current workspace?

for example

if len(windows) > 1:
[gaps]
outer.left = 10

else:
[gaps]
outer.left = 0

anyone know if anything like this is possible?
thanks!
