Can SMD footprints designed for wavesoldering be soldered using reflow process especially in the case of resistor type 1206?

Yes, you can reflow solder SMT parts with pads designed for wave soldering [including 1206] providing that you design your stencil apertures properly. It's a momma, poppa, baby bear situation. * Wave solder sized apertures will put too much paste on the pads * Reflow sized apertures will put too little paste on the pads * Somewhere in between is just right

As a side, we don't wave solder passive components larger than 0805
