I have been looking at putting together Saim-Hann and Yme-Loc armies lately.
The smaller mounted guardian units are a particular attraction, with or without Wraithguard.

Getting 2 or 3 Farseers into the army (commander and farsight) is highish on my priorities.

Looking in more detail the Mounted Farseers seem somewhat in-effective as combat troops.
Because the character is attached to a unit that has CC 6+ the MW EA+1 is relatively irrelevant.

The mounted farseer in the Yme-Loc list essentially comes free with the Swords of Vaul Warhost,
so whilst coming with a fairly expensive formation seems ok. However given that the current list
allows aspect warriors to be mounted in the tanks it might be nice to allow the farseer to also
dismount and put his Witchblade to more direct use.

The mounted farseer in the Saim-Hann list by comparison seems a rather expensive upgrade
at 50 points given it can only be added to a CC 6+ unit. I realise that Farsight and Commander
are both pretty useful additions. But elsewhere you seem to get the extra attack on a more
capable unit. For example the Wild Rider commander add on the basic jetbike formation
comes at 50 points. I seem to remember previous lists typically priced a regular Farseer
unit upgrade at 50 points, with its integral CC 4+. Perhaps allow a Mounted Farseer as a
unit upgrade, with appropriate stats, rather than as a character.

We could perhaps look at reducing the cost, or we could look at allowing them to be added to Wild Rider units.

Adding a Farseer character to a Wild Rider unit would certainly help.
As it currently stands that would give the unit three attacks:
CC 4+, CC EA+1 and CC MW EA+1, which seems a lot.

A cheaper Farseer would certainly help me with putting together an army list.

But I think my preference would probably be to provide the upgrade as a separate unit.
I know that I have modeled a mounted farseer as a viper like unit on a single base.
What have other people done?

So anyway I'd vote for something like:

Mounted Farseer
Light Vehicle, move 35 cm, AR 4+, CC 4+, FF 5+, small arms, Witch Blade (base), MW EA+1
Skimmer, Invulnerable Save, Farsight, Commander, May summon the Avatar.

Basically a Vyper without the gun but with good CC and the standard capabilities for 50 points.

Not certain I expressed myself very well with the costing for the Wild Riders.
A basic 6 strong jetbike formation for 200 points gets an extra unit (wild rider) for 50 points.
Adding a Mounted Farseer unit as an upgrade seems a neat similar solution to my "issue".
