Ofcourse its possible! at high scores (>92) standard english actually scales better than advanced english
I put My subjects in (4u maths, 3u maths, physics, chemistry and advanced english) into matrix's atar calculator
Then I set the HSC mark for the not english subjects to 95, then I set advanced english to 95
That gave me an atar of 99.85
I changed it to eng standard, it gave me an atar of 99.9
I changed the english mark to 92, my atar was calculated to be 99.80 for both standard and advanced
But yeah anything lower than 92 advanced would have been better (e.g. 85 gave me 99.4 atar for advanced, 99.25 for standard)
And standard english is quite hard to get a band score
But its certainly possible, and if you end up smashing standard english, you'll actually do better than an same scored advanced student in your english contribution to ATAR
