You can do something along the lines of
<block myblock> / trials = [1-8 = noreplace(vowel, consonant)] </block>
<trial vowel> / stimulustimes = [0=vowel; 1500=blank; 2000=blank] / validresponse = ("v", "c") / correctresponse = ("v") / beginresponsetime = 0 / responseinterrupt = frames / trialduration = 2000 </trial>
<trial consonant> / stimulustimes = [0=consonant; 1500=blank; 2000=blank] / validresponse = ("v", "c") / correctresponse = ("c") / beginresponsetime = 0 / responseinterrupt = frames / trialduration = 2000 </trial>
<text vowel> / items = vowels / erase = false </text>
<item vowels> / 1 = "A" / 2 = "E" / 3 = "I" / 4 = "O" </item>
<text consonant> / items = consonants / erase = false </text>
<item consonants> / 1 = "B" / 2 = "F" / 3 = "J" / 4 = "P" </item>
<shape blank> / color = white / shape = rectangle / size = (100%, 100%) / erase = false </shape>
(works the same with <picture> instead of <text> stimuli).
