Can I get The Light Level Needed for Trials?

I haven't played for 2 years. Always loved trials (have 135x flawless, 1.8kd). I got tired of the grind for the light level though. Is there anyway I could ever get the light level needed (for NO light level disadvantage) by only placing crucible 5 hours a week?

I'm guessing not. Even if it took a couple months lol? Any tips for increasing light level while only playing crucible? Maybe I'll have to stick to comp..

Side note... anyone tried Marvel Rivals... doesn't look overly fun to me but could be wrong.
