First of all, you can make use of the 'rescale' argument of
plot.igraph, to make sure that the layout that you supply is not
scaled.

To get the layout itself, you'll need to fix some x and y coordinates
for the vertices. This can be done with layout.fruchterman.reingold,
and the 'minx', 'miny', 'maxx', etc. arguments. Basically you'll need
to fix all the 'y' coordinates and the 'x' coordinates of the top row,
right?

If the automatic layout is not good enough, you can update it by hand,
e.g. by plotting it via tkplot() first, adjusting it, and then calling
tkplot.getcoords() to get the coordinates.

This'll require some experimenting, but it should be possible.

Best,
G.
