It is a big jump, , 18 teeth , you could pick up a smaller big chairing too..
or make the small one a 36 52 combo, those were really common
on bikes in the past.
50, 34 or 48 34 are the new thing..
should be able to change chainrings without removing
need a 5mm allen wrench and a special but inexpensive tool
to hold onto the nut on the opposite side,ring nut has notches
Your local bike shop is where i'd look 1st.
