If you are basically talking about removing one chainring and the front derailleur then no, you will be reducing your gear range and there is an inevitable compromise one way or the other to take into account.
Consider riding around with your set up as it is without using one of your current chainrings as a test.
To gain good climbing range you'd need a wide/r range cassette with bigger cogs. To then increase top speed you'd need to increase the size of your chainring within the limit of how big a front chainring would fit with safe clearance for your frame (chainstay).
A good set up suitable for you personally will depend on the intended type of riding you do and the terrain you're mostly riding on.
In simple terms think of 1x with an average 30t chainring and a big cassette as aimed more at gaining low climbing range at the expense of all out top speed. 😉
