UEF Scu produces 11 mass and 1,020 e. To reach the 10,000 mass/s and 1,000,000 e/s the limiting factor is the e you need 980 scus with ras for reaching the e income and 909 scus with ras to reach the mass income. Basically possible
It costs 6600 mass so you have to pay 6,000,000 mass to built 909 scus.
To built a salvation next to a paragon sounds stupid. Once got a paragon you need to be prepared for this with lots of t3 engis or scus. Then you simply spam sams nuke defs shields arround para and assist shields with lots of built power and get pd, t1 pds next to para and offensive you start spamming salvations, koloss and czar. While all this is going on you need to start new paragons like 2-4 at different places. Templates (spread sam & nuke def // shielding & t1 pd) are very useful for paragon case. But a salvation next to a paragon sounds like you are playing at very very low late game experience level
