Bit of a noob here,

so they have been complaining and fighting about what to do with bitcoin and its scaling issues....
some say change the block size, others disagree etc etc etc security.... open source... etc etc etc

Ok...

IF BTC wants to give the finger to BTU its quite simple there no need to change the block size silly silly
change the interval and the reward per interval.

eg. bitcoin block every 10 minutes+-... 12.5 btc reward "yay" block size 1mb +-
change to block every 1 minute 1.25btc reward per block "yay" block size 1mb (same same but different) scaled 10 fold.
all bocks will be valued on the chain processing is done faster. which is what people want...

If you do variable block size couple of problems pools will wanna do bigger blocks first or withhold certifying big blocks buy other pools

this is what i see on the surface.......

Hash difficulty will equalize to make the 1minute block happen. so 2 weeks of shuffle shuffle and then bam scaled 10 fold... and if this problem happens again
change interval for 1 minute to 10 seconds etc etc...

that my 5c
