I used a lekkie 42t with a 34t rear cog, 26x2.15 tire. Only hill I had to use max throttle+pedal was one that is difficult to descend/ascend on foot.You'll be fine with 42t. Btw if you are getting the 42t from ali, the 46t ones are lighter. Since the 42t have a steel backing plate but the 46t are alu backed. This is for 9 speeds, do your research on weights. A 42t max capacity derallieur like the m6000 will handle 46t fine after B tension adjustment.

That derailleur is rated for a maximum 36t sprocket. Whether it will reach a 42T depends on the length of the derailleur hanger. You might need to use a Wolf Tooth Road Link or other hanger extender, and that will adversely affect shifting in the smaller sprockets.
Ive been using SLX M7000-11 for my 10 speed 11-46 cassette. Shimano recently also came out with a new Deore series that is redesigned to work with up to 46 tooth cassettes.
It depends on the terrain, Im running a 34 tooth chainring and a 11-46 cassette. Would not want any bigger chainring for the really steep climbs.

My Kona Wo has a double up front with a 36T big ring, if I match the Ebike conversion with a Lekkie 36t, it puts the chainline out another 10mm, If a go to a 42T Luna Eclipse with the larger Offset and a 11-42 (or 46) Cassete It will have the same chailine has my factory setup with current 36T chainring. Do I take a chance that the extra 10mm chainline will work or do I buy the bigger cassette and derailleur?
Is a 42 front and a 42 cog in the rear low enough for off-road use, hills etc.?

It depends on where you go. For normal offroad use, you would be more often in the 24-28t range with a 42t. Everything above is purely climbing. How big are the hills offroad you plan on riding on? Don't try to build a perfect bike for hills that might not even exist in your area.
