if you can just trim down any conifer willy nilly
Many (most?) will not regrow from old wood, so if you butcher it, it'll look butchered forever.
Bird nesting season now so if I were you I would just embrace its privacy and wildlife value, until you can afford to get it properly removed.
Maybe grow a climber up it so you get some flowers

Nothing.
If you don't like it, get rid of it. If you can't get rid of it now, then wait until you can.
