the LAA are working successfully toward that goal
While some (all-metal) types will be fine, with appropriate avionics etc, some others will be "interesting" when they come to look at airframe bonding... this is hugely important not just for lightning protection (you don't want the control linkages disappearing if you get hit) but for dealing with static when flying in IMC.
You may find it is a Pyrrhic victory in some cases, when you look at the airspace-mandated equipment carriage requirements for enroute IFR, and these will not go away.
IFR flight in the US Experimental category is workable to a significant degree because they don't require the carriage of very much.
