Instead of trying to remove the little nightmares you could parallel another 220ohm across each one. This will drop the effective restance down to 110 if you parallel a 220 across it
If you uses a 190 will make it around 101 ohms.
For the math incliend, here are two different formulas.
1/(1/R1)+(1/R2)) = effective value
or if you have two resistors
(R1 * R2)/(R1 + R2) = Results
So something around 190ohm will give you 100.
