When in trouble, in sci-fy, put a machine to do it for you
What that mean is basically a reminder than Darth Vader was a reality, and Star Wars have A TON of technology designed to replace organs and/or keep alive people.
With that in mind, you, oh so great Darth Incognitus need a machine than allow you control the response of your body against it's midiclorians.
If the force or your body stand in the way of you being more powerfull, You need to control them!
If you need an automatic control of your natural filtering organs, they can be replaced by synthetic versions of them specialy modified to make your midiclorian administration as you want.
What happend? your blood cells are not designed to do thatresist the influx of new Midichlorian? doesn't matter, replace the medula of your bones (which if i remember correctly, replace the blood lossed) for a machine than do replace blood BUT make it just in the way you need it for achieve your "Darth intentions" (pun intended).
Is your brain affecting the process? doesn't matter, put an artificial part of your brain than do exactly what your brain used to do OR put a machine than counterweight the efect of that part of your brain just in the right way to make the effect you want.
In time you'll become more and more of a machine Darth Incognitus!, but we all know than Power only respond to Inmortality! and all we know than Machines are inmortal!
PS: if you like my answer and are making something related to starwars, make a character kinda like a teck-priest and put the name 'Kradathon' in some way connected to it, you decide what the name means, it would be a cool way to say "thanks". :D
