Why not get 2 Elk tags and then 2 bear tags. Our Elk seasons do not over lap with deer seasons. But bear runs for about 6 months.
If you plan on hunting in a wilderness area, forget the ATV nothing with a wheel is allowed in wilderness area's not even game haulers that have the bicycle wheel can be taken into Oregons wilderness area's. But like I said you can drive right up to wilderness areas in a lot of places in Oregon's Cascade mountains. I don't know if you want to drive clear out to Oregon or not but I thought I would give you the info. anyway.
