Well, First of all,you are taking a chance something can go wrong. Now,ignoring that? This is the BEST time of year for what you're thinking. Cutting off the compact new growth with appropriate amount of aerial roots should over the next many long warm months gives it plenty of time to settle in.. a new location or a pot. And there should be enough time for the remaining stem to bud a new stem or two.
NOW, I say that Maward, with the idea you have a great filtered shade location, with surrounding plants thriving in that same lighting. Otherwise, you have to think twice about all of it.
Also,You got a lot of growth in 5 years time. That's quite a bit of stem if when you started it was typical Monstera nursery size. And the swirly pattern on the non woody stem shows a bonus attraction to variegated Monsteras. Just find them more shade.
