I don't know if there is still interest in this problem, but adjusting the
-ylabel()- margin as a function of the difference in maximum widths of the
two ylabels appears to work.

For example:

set obs 100
gen x = uniform()
gen y1 = uniform()*10
gen y2 = uniform()*100
gen y3 = uniform()*400
gen y4 = uniform()*90000

foreach i of numlist 1 3 {
qui sum y`i'
_natscale `=r(min)' `=r(max)' 5
local m`i' = r(max)
local l`i' = length("`m`i''") 

local j = `i' + 1
qui sum y`j'
_natscale `=r(min)' `=r(max)' 5
local m`j' = r(max)
local l`j' = length("`m`j''") 
local diff = (`l`j''- `l`i'')*2 

display "lengths: " "`l`i'' `l`j'' `diff'"

scatter y`i' x, ylabel(,angle(h)) xlabel(none) xtitle("") /// 
 ytitle(, margin(0 `diff'  0 0 )) name(gr1, replace)
scatter y`j' x, ylabel(,angle(h)) name(gr2,replace) /// 
 ytitle(, margin(0 0 0 0 ))
graph combine gr1 gr2, col(1) name(gr_`j', replace)
graph drop gr1 gr2
