There is no way around to heat up first chromospheric material to fill  
coronal
loops to produce the enhanced soft X-ray and EUV emission we see from
coronal loops (like in flares). Any heating mechanism that heats  
directly
in the corona, does not increase the local density, so we would not see
any loops.
