Yes sir. You can also do stupid things like remove the check valve from the CO2 input on the OEM keg tap and haz yourself a vacuum vessel.
Or remove the spear, fill the keg with weed and liquor, use a broom handle to make a hole for the spear, clamp a screen and a couple of coffee filters over the end that goes in the keg, and vacuum the tincture out into another keg…
