If you donate blood with low levels of cholestorol into a body with previously high levels of cholesterol, would there be any discernible effects?

It depends on the amount of blood given and amount in the body.

Say you have 4 pints of blood with HDLs at 100.  Add in 1 pint with HDLs at 20,you wind up with an end point of 5 pints with HDLs at 84.  So, in that case you'd see a drop in HDL levels.

However, various lipoprotein levels are primarily influenced by diet and activity, so after the initial change, lipoprotein levels would drift back to baseline unless significant lifestyle changes also occur.
