i copied a short video and inverted the color in second.mp4 by using the negate filter so the cross fade is from regular color to inverted color... then i just added the drawtext as the next item in the filter_complex
you can see the output here: http://www.dopelabs.com/video/crosstext.mp4
$ ffmpeg -i first.mp4 -i second.mp4 -filter_complex '[0:v]trim=start=0:end=2,setpts=PTS-STARTPTS[0_clip_1];[0:v]trim=start=2:end=3,setpts=PTS-STARTPTS[fadeoutsrc_0];[fadeoutsrc_0]format=pix_fmts=yuva420p,fade=t=out:st=0:d=1:alpha=1[fadeout_0];[fadeout_0]fifo[fadeoutfifo_0];[1:v]trim=start=1,setpts=PTS-STARTPTS[1_clip_2];[1:v]trim=start=0:end=1,setpts=PTS-STARTPTS[fadeinsrc_1];[fadeinsrc_1]format=pix_fmts=yuva420p,fade=t=in:st=0:d=1:alpha=1[fadein_1];[fadein_1]fifo[fadeinfifo_1];[fadeoutfifo_0][fadeinfifo_1]overlay[crossfade_1];[0_clip_1][crossfade_1][1_clip_2]concat=n=3[output];[output]drawtext=text="lets be friends":fontcolor=white:fontsize=40:box=1:boxcolor=red at 0.5:boxborderw=10:x=5:y=5[out]' -map "[out]" crosstext.mp4
