Added into a reply proposed changes (by me) in-lieu of those made by the original poster, to address the issues I had from above. And break up the essay.

Exhaust - Slow not touched or reduced to 25%, duration increased to 4sec, prevents target from using Flash while in effect. Summoner's Wrath: Prevents all actions not available while Rooted.

This would allow for a much longer but slightly reduced slow, with AS/AD hits still in effect, and eliminating the threat of Flash to counter the slow and escape/continue to chase. Summoner's Wrath providing the no-Rooted-casting effect build on the no-Flash without making it necessary to take that mastery since Flash is the biggest factor there anyway (followed by Arc. Shift, Rift Walk, etc.).

Ghost - Duration reduced to 9sec., MS bonus increased to 40% base. Summoner's Wrath: Increases MS bonus to 50% (100 MS would be 150 with mastery Ghost used) AND reduces the DURATION of slows applied AFTER Ghost is used by 25-30% (exact value TBD).

According to the initial Ghost changes, a Ghost'er would move much faster but for a shorter time, and would not travel nearly as far overall (assuming same movespeed base for each): 100 ft/s x 10s = 1000ft. 127 ft/s x 10s = 1270 ft in same time. 145 ft/s x 6s = 870 ft. This is much faster but not for as long a distance, a sprint not a marathon, emulating rather than differing from Flash. The original suggestion also has no mastery increase to the speed, rather reducing slow applied while Ghosting. This is only a slight improvement in my eyes, changing to little with the already meh. Speed/Time adjustment.

With my proposed Ghost changes, the distance traveled is 10 units shorter initially (1260/1270) but the same between after Summoner's Wrath (1350/1350), while increasing the actual speed at which you move, making it easier to escape/catch someone who has Flash/another escape without affecting the ground covered. My Summoner's Wrath change retains a smaller increase to the Ghost bonus MS, but adds a further benefit. Critically, I don't think Ghost should make slows less effective, as Exhaust is a counter to Ghost as well as Flash already (just not effective enough on Flash, hence discussion). Rather, I think Ghost should make slows last a shorter time, so that the Ghost duration will still kick in but the slow can potentially cripple your move speed and POTENTIALLY serve to counter Ghost. As it should be. Wither, for example, at max rank slows for 95% (massive) and lasts 5 seconds with an accelerated, intensifying slow (increasing over time, faster if shortened). Cut for 25-30% (exact value TBD), Wither would last 3.5 second but still apply the full 95%. Still crippling, but shorter and allowing the other 5.5 seconds of Ghost to have full effect as usual. Ghost also still ignores unit collision, allowing faster movement because of a more direct route.
