Combining 3 imagemagick cli parameters into one ImageMagick.NET code - imagemagick

Question

Hey all I have these 3 imageMagick scripts (command line arguments) that I am trying to combine into Imagemagick.NET code.
First (merging 2 images together):
convert ^
( testingl.jpg -resize 610x440^^ -gravity West -extent 1080x440 ) ^
( testingr.jpg -resize 610x440^^ -gravity East -extent 1080x440 ) ^
blend_mask.png -blur 0x7 ^
-composite bothImagesMerged.jpg
Second (Create 2 round objects with photo inside):
convert lisa.jpg -resize 100x100! ^
null: ( -size 100x100 xc:black -fill white -draw "circle 50,50 50,88" ) ^
-alpha off -compose copy_opacity -layers composite ^
null: ( -size 100x100 xc:"graya(100%,0)" -fill black -draw "circle 50,50 50,90" -blur 0x5 ) ^
-compose dstover -layers composite ^
-background none -gravity center +smush -25+0 ^
roundImageLisa.png
convert homer.jpg -resize 100x100! ^
null: ( -size 100x100 xc:black -fill white -draw "circle 50,50 50,88" ) ^
-alpha off -compose copy_opacity -layers composite ^
null: ( -size 100x100 xc:"graya(100%,0)" -fill black -draw "circle 50,50 50,90" -blur 0x5 ) ^
-compose dstover -layers composite ^
-background none -gravity center +smush -25+0 ^
roundImageHomer.png
Third (Write text on top of photo):
convert -size 1080x440 xc:none -gravity center ^
-font arial -pointsize 40 ^
-stroke black -strokewidth 2 -annotate +-330+-150 "Lisa Simpson" ^
-stroke black -strokewidth 2 -annotate +330+-150 "Homer Simpson" ^
-background none -shadow 520x3+0+0 +repage ^
-stroke none -fill white -annotate +-330+-150 "Lisa Simpson" ^
-stroke none -fill white -annotate +330+-150 "Homer Simpson" ^
bothImagesMerged.jpg +swap -gravity center -geometry +0-3 ^
-composite textOverImg.jpg
If I was able to combine all 3 of those then the output would look something like this:
I've tried to put all of them into a one-liner but can not seem to find the correct way (order mainly) into doing so.
I do have some code that produces the round images in C#:
Bitmap bitmap = new Bitmap("lisa.jpg");
MagickImageCollection images = new MagickImageCollection();
IMagickImage roundImg = null;
IMagickImage mask = new MagickImage("xc:black", 100, 100);
mask.Settings.FillColor = MagickColors.White;
mask.Draw(new DrawableCircle(50, 50, 50, 90));
mask.HasAlpha = false;
roundImg = new MagickImage(bitmap);
roundImg.Resize(100, 100);
roundImg.Composite(mask, CompositeOperator.CopyAlpha);
roundImg.Draw(new DrawableStrokeColor(MagickColors.Black),
new DrawableStrokeWidth(1),
new DrawableFillColor(MagickColors.None),
new DrawableCircle(50, 50, 50, 90));
IMagickImage shadow = new MagickImage("xc:none", 100, 100);
shadow.Settings.FillColor = MagickColors.Black;
shadow.Draw(new DrawableCircle(50, 50, 50, 90));
shadow.Blur(0, 5);
roundImg.Composite(shadow, CompositeOperator.DstOver);
images.Add(roundImg);
images.First().BackgroundColor = MagickColors.None;
IMagickImage result = new MagickImage();
result = images.SmushHorizontal(-35);
result.Write("lisa_round.png");
mask.Dispose();
shadow.Dispose();
result.Dispose();
images.Dispose();
Assistance would be great! #fmw42
