Have any other rooms in your house that aren't being used? Whenever I get the upgrade bug, I make other systems instead of upgrading my main one. Other rooms can often be closer to that golden ratio with regard to acoustics, and less can often end up being more in those situations. My bedroom system only has a pair of budget DIY two-ways and a Chi-fi Bluetooth amp and it's bloody fantastic. So much so, I spend some time with it every day.
My main system often causes me to delay going to bed. Having a sweet side system in there that I really dig, saves me some sleep. OTOH, it can keep me in there longer than I should in the AM too so, there is that.
I also have break down systems I can set up on a table in 5 minutes and stash it in a box in my closet just as quickly, and those are worth doing too. Great plan B systems for when hurricanes send me to friends or relatives houses, who like music, but have no real systems. Now they request I bring them with, even just to visit.
There are no rules in the code of man that says we can only have one system. Sometimes I need a system for my other hobbies that put me in other parts of the house away from my main system and this conflicts me sometimes when I want to do both music and whatever at the same time.
