Older (2014) Scott Spark 3x10 to 1x12 conversion...advice.

Hey all, I have a older Scott Spark 920, that has a 3x10 shimano drive train. I want to race the bike in XC in the upcoming season, but convert it to a 1×12. I already have an ethirteen helios cassette, SRAM X01 eagle shifter and derailleur. 12 speed chain also. So ... looking for advice on a crank set that will work. BB is pressfit, 71. Will I have any issues with chainline, etc.? Thx so much for any help!
